AWS::IAM::Group
Creates a new group.
For information about the number of groups you can create, see Limitations on IAM Entities in the IAM User Guide.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
JSON
{ "Type" : "AWS::IAM::Group", "Properties" : { "GroupName" :
String
, "ManagedPolicyArns" :[ String, ... ]
, "Path" :String
, "Policies" :[ Policy, ... ]
} }
YAML
Type: AWS::IAM::Group Properties: GroupName:
String
ManagedPolicyArns:- String
Path:String
Policies:- Policy
Properties
GroupName
-
The name of the group to create. Do not include the path in this value.
The group name must be unique within the account. Group names are not distinguished by case. For example, you cannot create groups named both "ADMINS" and "admins". If you don't specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the group name.
Important
If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.
If you specify a name, you must specify the
CAPABILITY_NAMED_IAM
value to acknowledge your template's capabilities. For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates.Important
Naming an IAM resource can cause an unrecoverable error if you reuse the same template in multiple Regions. To prevent this, we recommend using
Fn::Join
andAWS::Region
to create a Region-specific name, as in the following example:{"Fn::Join": ["", [{"Ref": "AWS::Region"}, {"Ref": "MyResourceName"}]]}
.Required: No
Type: String
Update requires: Replacement
ManagedPolicyArns
-
The Amazon Resource Name (ARN) of the IAM policy you want to attach.
For more information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference.
Required: No
Type: Array of String
Update requires: No interruption
Path
-
The path to the group. For more information about paths, see IAM identifiers in the IAM User Guide.
This parameter is optional. If it is not included, it defaults to a slash (/).
This parameter allows (through its regex pattern
) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! ( \u0021
) through the DEL character (\u007F
), including most punctuation characters, digits, and upper and lowercased letters.Required: No
Type: String
Pattern:
(\u002F)|(\u002F[\u0021-\u007E]+\u002F)
Minimum:
1
Maximum:
512
Update requires: No interruption
Policies
-
Adds or updates an inline policy document that is embedded in the specified IAM group. To view AWS::IAM::Group snippets, see Declaring an IAM Group Resource.
Important
The name of each inline policy for a role, user, or group must be unique. If you don't choose unique names, updates to the IAM identity will fail.
For information about limits on the number of inline policies that you can embed in a group, see Limitations on IAM Entities in the IAM User Guide.
Required: No
Type: Array of Policy
Update requires: No interruption
Return values
Ref
When you pass the logical ID of this resource to the intrinsic Ref
function, Ref
returns the GroupName
. For example:
mystack-mygroup-1DZETITOWEKVO
.
For more information about using the Ref
function, see Ref
.
Fn::GetAtt
The Fn::GetAtt
intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.
For more information about using the Fn::GetAtt
intrinsic function, see Fn::GetAtt
.
Arn
-
